Venice is a city in northeastern Italy and the capital of the region of Veneto. It is built on a group of 126 islands that are separated by expanses of open water and by canals; portions of the city are linked by 472 bridges. The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po and the Piave rivers (more exactly between the Brenta and the Sile). As of 2025, the city proper (comune of Venice) has 249,466 inhabitants, nearly 50,000 of whom live in the historical island city of Venice (centro storico), while most of the population resides on the mainland (terraferma), and about 25,000 live on other islands in the lagoon (estuario). Together with the cities of Padua and Treviso, Venice is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million. The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC. The city was the capital of the Republic of Venice for almost a millennium, from 810 to 1797. It was a major financial and maritime power during the Middle Ages and Renaissance, and a staging area for the Crusades and the Battle of Lepanto, as well as an important centre of commerce—especially silk, grain, and spice, and of art from the 13th century to the end of the 17th century. The then-city-state is considered to have been the first real international financial centre, emerging in the 9th century and reaching its greatest prominence in the 14th century. This made Venice a wealthy city throughout most of its history. For centuries, Venice possessed numerous territories along the Adriatic Sea and within the Italian peninsula, leaving a significant impact on the architecture and culture that can still be seen today.
